      • Does taking ratio of eta-bins in second end cap background need uncertainty?
    • 11-02-2017: Run13 W+/W- vs. Lepton Rapidity for Endcap and W charge asymmetry vs. lepton rapidity

      • Investigate the endcap charge separation cut
        •  fix amplitudes, widths, etc.

      • Issues: second EEMC background doesn't continue to fall as QCD background is expected to. Why?
    • 04-23-2018: W+/W- Update
      • Explains second endcap background
      • Shows some distributions
      • Looking for suggestions: Fit second endcap background with exp. function
    • 05-07-2018: W+/W- Update
      • Shows and compares results of using exp. function for second endcap background.
    • 05-30-2018: W+/W- Update (Prelim. Attempt)
      • Uses second EEMC fit method
      • Comments:
        1. Show larger background distributions on linear scale. Log scale plots start at y=1.
        2. RW endcap bin need some consideration when showing on plots. The e+ and e- have different eta distributions.
        3. Folded in the Fit-MC sys. error wrong. I used a relative error as an abs. error
        4. Fit to second EEMC background is under estimating. Large error bars may be resulting in smaller slope value. Have a call with Carl to discuss.
        5. Chi2 probability for data - MC comparisons seem wrong.
